To use the library, you must have an MP solver that eplex can use. This
can be an open-source solver such as the COIN-OR project's CLP/CBC solvers,
which is distributed with ECLiPSe, or a commercial solver such as 
XPRESS-MP or CPLEX. Your ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP> should be configured to load in a
`default' solver if there is more than one available.

manual's Eplex chapter for details for how to install the solver.</FONT>
</DL>
 
When configured properly, the library can be loaded with the directive:<BR>
<BR>

	<TABLE CELLPADDING=10>
<TR><TD BGCOLOR="#CCCCFF">
	<BLOCKQUOTE CLASS="quote"><PRE>
:- lib(eplex).
</PRE></BLOCKQUOTE></TD>
</TR></TABLE><BR>
This will load the library with the default external MP solver.<BR>
<BR>
You probably need a valid license in order to use an external commercial solver.<BR>
